            Bug ID: 358207
           Summary: kmail crashes (segfault) when replying to an email
           Product: kmail2
           Version: unspecified
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: sybren at stuvel.eu

Kmail crashes (segfault) when trying to reply to an email. All I have to do is
press the [R] key or click the Reply button to make it crash. This makes KMail
useless for me, which is why I marked this issue as "Grave".

This is the stack trace, with as many debug symbols as I could install:

Reproducible: Always

Steps to Reproduce:
1. Start kmail
2. Reply to an email
3. Crash

Actual Results:  
*** KMail got signal 11 (Exiting)

Expected Results:  
A new window that shows the email composer.

I'll attach the console output as well.
